~325whp on 550cc's?
I have a set of 550cc injectors and was wondering if they will be good for ~325whp? I have a adjustable fpr and was thinking about setting the fpr at ~55psi. will they be enough?

yes, I made 311 on DSM 440CC before I had to change them out so 550CC should hit 325 no problem.
I am assuming this is D or B series.

damn, u must be at 100% duty cycle. 350whp w/ base fuel pressure at 40 psi should be fine on 550cc

If you run 10psi of boost or less, 55psi wouldn't be bad, as that's making the fuel pump push up to 65psi (stock fuel reg is 1:1 rising rate).
325whp with 550's would probably get you around 85-90% duty cycle, which is about as far as you want to take injectors. You could get towards 400 with a good fuel pump and a good bump in fuel pressure, but if it ever spikes (or you want more later), you're SOL.

i dont reccomend it either. it was a band-aid.
just couldnt get anything but 440cc to work

240cc = 180-190whp
310cc = 200-220whp
370cc = 220-280whp
440cc = 280-330whp
550cc = 330whp-380whp
660cc = 380whp-425whp
720cc = 425whp-475whp
880cc = 475whp-525whp
1000cc = 525whp-600whp
